Rear suspension help!

[Joelang33]

I started to realize some swaying side to side under hard throttle pulls and especially going 80+ mph. feels like something going on in the rear of the car. Its a 2016 GT with whipple supercharger and airlift suspension. I dont think its an issue with the bags as they seem to be holding pressure fine. i also am hearing a click noise when shifting gears occasionally. Anyone have any thoughts / ideas?

Likely a rear wheel hub is gone out. Jack up the car and see if you can wobble a wheel by rocking it with a bear hug.

clicking noise and unpredictable handling at speed are giveaways. I've had to replace both rears twice. Average time to failure is ~30k miles on my car.

Take a look at the differential bushings too. You may have one or more that are torn.

If you have any toe out in the rear it will act strange. If you have a good bit of toe out it will almost be scary to drive.

car was aligned after bag install and has been fine for around 20,000 miles. that is why i am wondering if it is wear and tear on something

BOLO for something like this.
